much more durable in construction and effective in operation; and it consists, essentially, of a skein secured to the spindle, a box inclosing said skein and adapted to rotate thereon, an annular shoulder provided on the spindle, a cap-nut rotatably mounted on said spindle and provided with an annular recess adapted to journal said annular shoulder on the spindle, said nut having a screw-threaded engagement with said axle-box, the various parts of the device being constructed and arranged in detail, as hereinafter more particularly described.

Figure 1 is a side elevation of the righthand end of an axle and box mounted thereon. Fig; 2 is a central longitudinal sectional view of the same. Fig. 3 is a similar view to Fig. 2, showing the alternative form of capnut.

For further description of my invention reference is made to American Patent No. 726,383.

Referring to the drawings, A denotes a metal axle formed with a spindle a of any construction, but preferably tapering, as shown, having a reduced screw-threaded end a. An annular shoulder a is provided on the said spindle a for a purpose hereinafter to be described.

B is an axle-skein which fits the axle snugly and is retained in position by its threaded portion 5 engaging a threaded end a of the axle. A slot 6 extends through the end of the skein and through the screw-threaded portion of the spindle, whereby after the skein has been screwed to the desired position a key may be inserted therein and the spindle and skein thus securely locked together. Before the skein is placed in posiscrewed thereon are held much more securely in position, and the weakness hitherto experienced at this point due to the reducing of the diameter of the axle to form a spindle is done away with. The axle-box E is secured in the wooden hub of the wheel by any desired means, but preferably by means of the nut e, screwed on the upper screw-threaded end e of the box. The box rotates upon the skein B and has its outer end closed and formed on the inside with an oil recess or chamber 6 Referring to Fig. 3, there is here shown a modification of the cap-nut in which the end of the box is exteriorly threaded and the capnut is interiorly threaded, which secures a much firmer fastening.

The advantages of my new construction are that the spindle is greatly strengthened by the annular shoulder M, which overcomes, as hereinbefore mentioned, the weakness usually producedon reducing the axle to form a spindle at that point.

What I claim as my invention is 1. In a hub-attaching device in combination a tapered spindle, an annular shoulder provided on the inner end thereof, a tapered skein secured thereto, a tapered box inclosing said skein and provided with an interiorly-screw-threaded nut, a cap-nut having a screw-threaded engagement with the end of said box, and an annular recess provided in said cap-nut adapted to fit closely to the annular shoulder on the tapered spindle as and for the purpose specified.

2. In a hub-attaching device in combination a tapered spindle, a tapered skein secured thereto, a keyway extending through said skein, and spindle, a key fitting therein, a tapered box inclosing said skein and adapted to rotate thereon, an annular shoulder provided on said tapered spindle, a cap-nut lin and State of New York, this 20th day of raving a screw-threaded engagement With February, 1905.
